My forum at https://community.yinyanghouse.com/ has been working fine for a year or so. This morning I upgraded to 1.8.0 beta (I’m pretty sure that’s the latest) and I saw no errors during the upgrade. Now, however, I see just my custom css/html in the my header, etc. and no forum and I can’t get into admin (or I can, but I just get my header and footer)
How do I debug this and get my forum operating again?
